Abstract

An object of the present invention is to provide a temperature-adjustable futon that can keep the lower body of a sleeping person better than the upper body and can change the overall heat-retaining property.
SOLUTION: Six towel towels 2 having the same material, thickness and width but different lengths are stacked in order of length from the back side of the futon 1, and one end of each is attached to the end on the side where the sleeper M is hung. The mattress is sewn together so that the thickness of the futon 1 gradually increases from the end on the side where the upper part of the sleeper M is hung to the entire length. Even if it is folded at one place within the predetermined area, the length can cover the whole body of the sleeping person M so that even if the room temperature changes within a certain range, it can be used without folding with one futon 1 By changing the position, the overall heat retention was changed while maintaining the state of head cold foot heat, so that it was possible to sleep in a comfortable state.

Description

  The present invention relates to a commonly used hanging bag.

  Common quilts are roughly divided into winter, spring / autumn, and summer, and different thicknesses are used depending on the season. However, at the turn of the season, the temperature fluctuates greatly, so even if you use a quilt that suits the climate, you suddenly get cold during sleep and wake up and put on other thin futons. It may be replaced with a thick futon. In addition, it may be troublesome to have such a trouble, and it may catch a cold because of perseverance in a cold state. On the other hand, if you are using a thin summer quilt and it gets cold, it may be too hot if you stack another quilt or replace it with a thick quilt.

  In addition, when using a towel as a quilt in summer, the upper body is comfortable but the lower body is cold and cannot sleep well due to a decrease in room temperature due to cooling. In such a case, you usually hang another towel on the lower body side to warm the lower body. In this way, even if you sleep well, the towel you hang on the lower body side when you turn over Often, they wake up again due to the cold of the lower body.

On the other hand, Patent Document 1 describes that a portion of a towelet that is hung on the abdomen (lower body) of a sleeping person is made thicker by doubling or sewing another fabric. If this towel is used, the lower body of the sleeper is kept warmer than the upper body, and even if the sleeper turns over, the heat insulation effect does not deteriorate, so the problem of the conventional towel towel that it is impossible to sleep well due to the cold of the lower body is solved Is done.

  However, although the towelette described in the above-mentioned patent document 1 is formed thicker than the part to be hung on the upper half of the sleeper, it is generally thin for use in the summer. Therefore, when the temperature is slightly lowered, the whole body may be felt cold and may not be able to sleep. Therefore, at the turn of the season between spring and autumn, prepare a summer or spring / autumn one that is slightly thicker than this towel, and then use this towel and another one depending on the room temperature. It is necessary to use different tons.

  An object of the present invention is to provide a temperature-adjustable futon that can keep the lower body of a sleeping person better than the upper body and can change the overall heat retention.

In order to solve the above-mentioned problems, the temperature-adjustable futon of the present invention has a stepped shape with a stepped thickness from the front end portion hung on the sleeper to the rear end portion hung on the lower body , The step of the stepped surface is made equal to the thickness of the thinnest tip portion, and the pitch between the steps is the same, and the position of each step of the stepped surface or the bisected position between adjacent steps It is possible to change the thickness of the tip part to a thick state while maintaining the shape of the stepped surface by folding back from, improving the heat retention while maintaining the head cold foot heat state, and covering the whole body of the sleeping person even in the folded state The length was possible.

  In other words, when the room temperature is high, do not fold back the part that can be hung on the upper body of the futon sleeper, and use the extra part on the side that is hung on the lower body, so that the sleeper can be kept in a state of low heat retention as a whole. The lower body can be kept warmer than the upper body, and when the room temperature becomes low, the part that can be hung on the upper body of the sleeper is folded in one place within a predetermined area in the longitudinal direction, and pulled to the head side of the sleeper. As a result, the overall heat retention can be improved.

  Here, if the thickness is gradually increased over the entire length from the end portion on the side of the sleeper's upper body, the heat retaining property can be finely adjusted by changing the folding position.

  Further, by increasing the thickness of the portion that is hung on the lower body of the sleeping person, compared to the sum of the thickness of the parts that are overlapped when the portion that is hung on the upper body of the sleeping person is folded at a predetermined position in the longitudinal direction, Even when folded and used, the heat retention on the lower body side of the sleeping person can be reliably maintained higher than the heat retention on the upper body side.

  As described above, the temperature-adjustable futon of the present invention can keep the lower body of the sleeping person better than the upper body in a state where the overall heat retention is low if used without being folded, and by folding and using the entire body, Since the heat-retaining property is improved, an appropriate heat-retaining property can be obtained according to the room temperature, and it does not become too hot or too cold as in the prior art.

  Therefore, if this temperature-adjustable futon is used, it is possible to sleep in a comfortable state for a long period mainly in the summer. In addition, it is not necessary to prepare different types of sleeping bags with different heat retention properties at the turn of the season between spring and autumn, so it is possible to reduce the time and effort required to put the futon into and out of the closet.

  In addition, when the part that is hung on the upper body of the sleeping person is folded, the thickness of the part that is hung on the lower body of the sleeping person is made thicker than the sum of the thickness of the parts that are overlapped. As in the case where there is no sleep, the heat retention on the lower body side of the sleeping person is higher than the heat retention on the upper body side, so-called head cold foot heat can be achieved, which makes it easier to sleep.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, this temperature-adjustable futon 1 is formed by stacking and sewing six towel towels 2 having different lengths. It is formed to become thicker. Therefore, as a whole, the portion hung on the upper half of the sleeper M is thinner than the portion hung on the lower half and can be folded. Further, the overall length is considerably longer than that of a normal quilt, and as will be described later, even if the portion that can be hung on the upper half of the sleeping person M is folded at one place in a predetermined region in the longitudinal direction, It can be covered.

  Each towelette 2 is made of the same material, thickness (4 mm) and width (1400 mm), and is cut so that its length changes from 400 mm to 2400 mm at a pitch of 400 mm. Then, as shown in FIG. 2 (a), these towel towels 2 are overlapped in order of length from the back side of the futon 1, and one end of each is matched with the end on the side on which the sleeper M is hung. It is sutured in a state. Thereby, the part hung on the upper body of the sleeper M can be folded at the positions T1 to T4 shown in FIG. 2A and used in the states shown in FIGS. 2B to 2E, respectively. It has become.

  Here, if the length L of the effective area when using the futon 1 (the area covering the whole body of the sleeping person M) is 1600 mm, the thickness of the effective area in each use state of FIG. .

  As apparent from Table 1, in each use state of FIG. 2, the thickness in the effective area changes in five stages by a multiple of the thickness of one towelette 2, and the sum of the thicknesses of the portions to be overlapped by folding. The thickness (the thickness of the lower body side end portion of Table 1) of the sleeping person M is thicker than (the thickness of the upper body side end portion of Table 1).

  Therefore, when the room temperature is high, the temperature-adjustable futon 1 does not fold back the portion of the futon 1 that can be hung on the sleeper M, but the end on the side that can be hung on the lower half, as shown in FIG. By using it excessively, it is possible to sleep coolly in a state where the overall heat retention is low, and the folding position is changed in order from the state of FIG. 2 (b) to the state of FIG. 2 (e) as the room temperature decreases. By pulling to the head side of the sleeper M and using it, the whole heat retention property can be raised moderately and it can sleep comfortably. In addition, in any use state, the lower body of the sleeping person is kept warmer than the upper body, so that sleep can be achieved in a state of head cold foot heat.

  In addition, although illustration is abbreviate | omitted, fasteners, such as a hook and hook-and-loop fastener which mutually engage, are attached to the edge part by which the sleeper's M is hung on the upper body side, and the site | part which overlaps with this edge part when turned up. This ensures that the folded state can be maintained even while sleeping.

  In this example, six towel towels each having a thickness of 4 mm and a length pitch of 400 mm are stacked, but by changing the thickness or the pitch of the length or changing the number of stacked sheets, The thickness range in the effective area when using a futon can be expanded without limitation, and by using a blanket or a thick cloth instead of a towel as a futon material, various specifications can be created.

  For example, if you create a futon with a specification that the thickness of one piece of material is 30 mm, the pitch of the length is 300 mm, and the number of sheets to be stacked is 8, and it is used in the same way as FIG. 2, the total length is 2400 mm, When the length L is 1700 mm, the thickness in the effective region changes in five stages of 30 to 180 mm, 60 to 210 mm, 90 to 210 mm, 120 to 240 mm, and 150 to 240 mm. The futon of this specification can be used for a long time as it can be used for both spring and fall.

  Furthermore, in the above-described embodiment, the thickness of the futon is gradually increased from the end portion on the side where the sleeping person is hung on the upper body, but as shown in FIG. You may make it thick in proportion to the distance from. Also in this case, for example, as shown in FIGS. 3B and 3C, by folding back at an appropriate position, the heat retaining property can be increased while maintaining the state of head cold foot heat.
